The present study was carried out to study the genetic variation, character correlation and path analysis of hybrids to understand the interrelationship of yield and it’s attributing quantitative traits. A field experiment was conducted on multicut sorghum during the season 2015-2016 and 2016-2017, to investigate the genetic variability and phenotypic correlation between some yield and growth characters in forage sorghum. The experiment was laid in a randomized block design (RBD) with three replications. Characters studied included: growth attributes likeplant height (cm), leaf length (cm), leaf width (cm), number of leaves, dry weight (q/ha) and green fodder yield(q/ha). All characters showed variability. The highest means were shown by green fodder yield 1025.6 (q/ha) followed by dry weight 226.71 (q/ha) and further by plant height 221.38 (cm). The greatest PCV and GCV was 16.49 and 14.53 by leaf width. Similarly, maximum heritability was for dry weight 98.61% followed by leaf width is 77.64%. The agronomic trait like leaf width showed positive and significant correlation with number of leaves, dry weight and green fodder yield (q/ha) and also have shown positive association among themselves. Leaf length negatively correlated plant height, number of leaves per plant, dry weight and green fodder yield. Direct effect was highest for leaf width followed by dry weight. The study of various developmental and productive traits like leaf width and dry weight are helpful for framing the effective breeding programme and selection of yield related characters.
